For what it's worth, the OSX API's seem to behave as follows:
* If you create a file with an non-UTF8 name on a HFS+ filesystem the
system automaticly encodes the name.
That is, open(chr(255), 'w') will silently create a file named '%FF'
instead of the name you'd expect on a unix system.
* If you mount an NFS filesystem from a linux host and that directory
contains a file named chr(255)
- unix-level tools will see a file with the expected name (just like
on linux)
- Cocoa's NSFileManager returns u"?" as the filename, that is when the
filename cannot be decoded using UTF-8 the name returned by the high-
level API is mangled. This is regardless of the setting of LANG.
- I haven't found a way yet to access files whose names are not valid
UTF-8 using the high-level Cocoa API's.
The latter two are interesting because Cocoa has a unicode filesystem
API on top of a POSIX C-API, just like Python 3.x. I guess the choosen
behaviour works out on OSX (where users are unlikely to run into this
issue), but could be more problematic on other POSIX systems.
